Do the -minw and -maxw values given as parameters in psp-gen and it's corresponding output given as input in MEME should be same? In the online version of MEME, for the -maxw values above 20 in psp-gen still gets input as 20. For example, for the motif width 6 to 50, on running MEME online and seeing the commands given as input, we find -minw value as 6 but -maxw for psp-gen to be equal to 20 whereas for motif width 7, both -minw and -maxw input in psp-gen is 7. Is it some error or something else? Kindly explain. Thanks in advance :)
